Which of the following is a neutralization reaction? a. naoh (aq) + hcl (aq)= nacl (aq) + h2o (1), b. pb(no3)2 + 2 ki= pbi2 + 2 kno3, c. agno3 +hcl= agcl + hno3, d. fe2o3 + hcl= fecl3 + h2o

A. NaOH (aq) + HCl (aq)  NaCl (aq) + H₂O (l).

Explanation:

A neutralization reaction is defined as the reaction of an acid with a base to form water and a salt. This reaction involves the combination of H⁺ ions and OH⁻ ions to generate water.

A. NaOH (aq) + HCl (aq) → NaCl (aq) + H₂O (l). IS A NEUTRALIZATION REACTION because an acid (HCl) reacts with a base (NaOH to form water and a salt (NaCl)

B. Pb(NO₃)₂ + 2KI → PbI₂ + 2 KNO₃. IS NOT A NEUTRALIZATION REACTION because there are not acid nor base reacting.

C. AgNO₃ + HCl → AgCl + HNO₃ IS NOT A NEUTRALIZATION REACTION because there is an acid (HCl) but not a base.

D. Fe₂O₃ + HCl → FeCl₃ + H₂O IS NOT A NEUTRALIZATION REACTION because there is an acid but not a base.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
